NFS: Fix attribute delegation behaviour on exclusive create
[ Upstream commit d054c5eb2890633935c23c371f45fb2d6b3b4b64 ]
When the client does an exclusive create and the server decides to store
the verifier in the timestamps, a SETATTR is subsequently sent to fix up
those timestamps. When that is the case, suppress the exceptions for
attribute delegations in nfs4_bitmap_copy_adjust().
